    Default Transmission question

    A friend of mine recently converted his TJ from 2.5l and 5 speed to 4.0 w/ Auto tranny. Now the tranny will not shift properly. He has to manually engage the gears. He says he used the donor vehicle ECM but is clueless as to why the transmission won't shift properly.

    Any ideas?

    Wiring and sensors for the TCM all hooked up correctly? Fluid levels good? Was the trans known good when he put it in?

    Haven't looked at it yet. He is deployed and his wife doesn't know what to look for. She said it's an auto tranny but you have to shift it like a manual. Otherwise the Jeep runs good.
